Okay i just swapped in the rb25det into my s13 and all wires are hooked up correctly but im not getting a spark.. heres what i have checked.. sry moderator for double posting but no one answered in the other section..

I checked:
Coilpack electrical connectors.. reads ohms and gets 12v under power
Fuel injection electrical connectors are getting 12v under power as well
I ripped the entire harness apart, whatever was a ground was checked to make sure its ground and grounded, so i can't see it being that.
The red light is on , on my ecu.. so that means it's receiving power, correct?
Fuel pump primes and turns off after 5-10 seconds, like it should but heres where i think it might be..
Injectors aren't wet after the motor cranks when i try to start it.. the injectors are suppose to release a small amount of fuel even though it's not firing right..

someone give me more shit to check please

thats exactly what it is... now if you want to be like that you wont get far.


take of your CAS and with the key in the ACC position spin the cas do you hear the injectors?...Good if you do. if not go over wiring.
now do you have the relays near the ecu plugged in? also do you have ignition signal wire hooked up? prob. not.;)

Check your vtage during cranking.10 v will turn a engine but not spark a dis.
Also check during cranking that the inj have 12v make sure there to constant not switched 12 v. And check start signal on the dash plug make sure it's geting 12v during cranking. Good luck.

Also trouble shooting is a art that some times needs to be in person not on a forum. But other peoples input helps to.

Wow someone answered , thanks . Everythings connected, and grounded. no burnt fuses, relays all plugged and workin. I think it's my ignitor chip cause now i checked the coil packs under 12v and i only get a reading of .3v so im guessin its the chip.. idk though
